Use Rhyzobug for the control of armoured scale insects.
Armoured scale insects
Diaspis boisduvalii, Aspidiotis nerii, Aonidiella aurantii, Aulacaspis spp., and other species of armoured scale insects.
How it works
Mode of action
Adults and larvae feed on all stages of armoured scale insects.
Eggs are laid underneath the scales.
Larvae are grey with a light longitudinal stripe. Fully grown larvae are about 3.5 mm long.
Pupae are orange-pink in colour and are attached to the plant surface with their rear end.
Adults are about 2.5 mm long, have a brown coloured abdomen and a reddish brown head and are entirely covered by hairs.
Small scales are consumed entirely. In larger scales feeding damage is visible as irregular holes in the scale cover.
|Pack size||500 adults.|
|Presentation||90 ml cardboard tube.|
|Food||Felt pad with sugar water.|
Directions for use
Apply Rhyzobug in the evening. Open the cap and tap the beetles directly on the plants. Be aware that adults may not fly away immediately after release.
The dosage of Rhyzobug depends on climate, crop and armoured scale density and should always be adjusted to the particular situation. Start introduction as soon as the first armoured scales are detected in the crop. Introduction rates in outdoor crops typically range from 500-3,000 per ha/release. Releases should be repeated once or twice. Consult a Koppert advisor or a recognized distributor of Koppert products for advice on the best strategy for your situation.
Optimal temperature for Rhyzobug are around 25°C (77°F). Lower temperature slows down the development of Rhyzobius lophanthae.
Can be combined with Aphytis melinus.
